Their committees work with the manufacturing and service industries, government, businesses and consumers to facilitate the production of British, European and International standards.
You may experience issues viewing this site in Internet Explorer 9, 10 or For coarse gradings the test may be performed on representative parts of sieve fractions obtained from the determination of the particle size distribution Clause 5 containing a sufficient number of armourstones.
Remove the warm test portion from the can and allow to surface dry. Where the test portion for water absorption is larger than the remaining part of the laboratory sample it shall be used as the freeze-thaw portion. Determination of the water content by drying in a e oven ISOTest sieves — Technical requirements 31383-2 testing — Part 2: Each piece of armourstone shall be marked clearly and durably with the allocated number.
Laboratory samples shall be transported in such a way that pieces of armourstone are not broken in transit.
The sample shall be reduced if necessary in accordance with the requirements e Clause 4 to produce the required test portion. The mass of the test portion in kilograms shall be at least twice the nominal upper limit of the grading in millimetres.

The test portion shall consist of one piece of armourstone or part thereof without open visible cracks.

The capacity of the balance shall be suitable to allow the wire basket containing the sample to be suspended and weighed in water.
Log In Sign Up. If a sampling increment of a heavy grading is too large for the preparation of the bulk sample, the procedure dn specified in 4.
If a sampling increment of a coarse grading is too large as test portion, one of the procedures as described in 4. NOTE For armourstone both een and preparation are to some extent dependent on the mass 113383-2 the piece of armourstone selected for the test. Second number of samples can directly be taken and sent to the laboratory together with the first number, or can be taken or sent to the laboratory if necessary depending on the test result of the first number.

NOTE 2 Steel slags might contain oxides of calcium and magnesium, which when in contact with water these mineral phases will react to form hydroxides with a resultant increase in volume.
Document Status Indicators The Green document status indicator indicates that the document is: The distance between the cross-sections shall be determined by the required quantity of the sampling increment.
Place the test portion in the wire-basket suspended from the balance and immerse them in the tank containing water with a cover of at least 50 mm of water above the top of the basket. Samples may also be taken at the discharge from a screen by the same method. All sampling increments shall be taken at the same sampling point.
Methods for sampling ENTests for general properties of aggregates — Part 5: For other purposes, in particular factory production control, other methods may be used provided that an appropriate working relationship with the test method has been established.
NOTE For guidance on numbers and sizes of samples and test portions for testing armourstone as specified in EN When this gives too large a sampling increment, it should be reduced by one of the methods described in 4.
Examine and record crack formation. Free to use BIM project management tool provides step-by-step help to define, manage and validate responsibility for information development and delivery at each stage of the asset life cycle in level 2 BIM projects. When using this table, the following possibilities for using samples for testing several properties can be taken into account: Depending on the source, this process might take place within months of extraction or extend over several decades.
Sampling from static batches should be avoided wherever possible since it is difficult to satisfy the principle of taking sampling increments at random from all parts of the batch, and hence segregation is likely to cause the sampling to produce biased results.
